Kate Upton was spotted at the U.S. Open Saturday, where she was snapped chowing down on a meaty sandwich while seated in the the Moët & Chandon suite.

The 21-year-old stunner—who recently won the coveted title of Model of the Year at the 10th Annual Style Awards—wowed in tennis whites on Day 13 of the U.S. Open, which is being held at the Billie Jean King National Tennis Center in New York.

She flaunted her famous curves in a fitted white dress with a scoop neck that highlighted her ample cleavage, pairing her classy ensemble with nude high-heeled sandals.

Upton, who was also photographed watching the action on the court with fellow model Karolina Kurkova sipped on champagne from a golden goblet (à la Leonardo DiCaprio), happily indulging in the food and drink at the annual sporting event.

While the model of the moment has certainly encountered her fair share of criticism, there's no question the blond beauty has successfully made the difficult transition from bikini model to high-fashion starlet, gracing both the covers of American Vogue as well as the Brazilian edition of the magazine this year alone.

"After my first Sports Illustrated cover, I felt terrible about myself for a solid month," she confessed. "Every single guy I met was either married or about to be married, and I felt like I was their bachelor present or something. I'm not a toy, I'm a human. I'm not here to be used. I am a grown woman, and you need to figure your s--t out."
